Scientists Call for Drastic Drop in Emissions. U.S. Appears to Have Gone the Other Way.

A report by a private research company found that U.S. emissions, which amount to one-sixth of the planet’s, didn’t fall in 2018 but instead skyrocketed. The 3.4 percent jump for 2018, projected by the firm, would be second-largest surge in greenhouse gas emissions from the U.S. since Bill Clinton was president.

The signals are blaring: Dramatic changes to our climate are well upon us. These changes — we know thanks to a steady drumbeat of alarming official reports over the past 12 months — could cripple the U.S. economy, threaten to make vast stretches of our coastlines uninhabitable, make basic food supplies scarce and push millions of the planet’s poorest people into cities and across borders as they flee environmental perils.

All is not yet lost, we are told, but the demands of the moment are great. The resounding consensus of scientists, economists and analysts tells us that the solution lies in an unprecedented global effort to immediately and drastically drop carbon emissions levels. That drop is possible, but it will need to happen so fast that it will demand extraordinary commitment, resolve, innovation and, yes, sacrifice.
